Investigation of Surface Crack Growth Behaviour Under Variable Pressure Fluctuations in Near-Neutral pH Environments
DownloadFall 2017
The goal of this investigation was to study the corrosion fatigue behaviour and mechanisms of surface cracks, semi-elliptical in shape, when exposed to near-neutral pH environments conducive to the environments experienced in the field. To better simulate field conditions, while avoiding the...

Investigation of Corrosion and Crack Morphology Behavior under Disbonded Coatings on Pipelines
DownloadFall 2015
Coating disbondment on pipelines is a common phenomenon that leads to exposure of the pipeline metal to the surrounding soil and ground water solutions. The exposure of pipelines to those corrosive environments is associated with development of corrosion and Stress Corrosion Cracking (SCC) on the...

Effects of Oxide Additions on the Corrosion Behaviour of Cr2O3 Based Ceramics in High Temperature Supercritical Water Environment
DownloadFall 2012
This investigation is aimed at developing ceramic materials applied in supercritical water, which is being considered as coolant for one of the next generation nuclear reactors. Cr2O3, a primary protective film on stainless steels, was found to be unstable in SCW due to the formation of soluble...

Developing a Predictive Model of Near-Neutral pH Stress Corrosion Cracking of Underground Pipelines
DownloadSpring 2014
Near neutral pH Stress Corrosion Cracking (NNpHSCC) on underground oil and gas pipelines is an issue facing industry today. Determining where NNpHSCC is likely to occur and grow is an important aspect to developing an Integrity Management Program. This work focused on developing a predictive...

Creation and Characterization of Ceramic/Polymer Bi-Continuous Composite Material for Hot-Bitumen Pipeline Coating
DownloadSpring 2015
Current composite materials base their capabilities from the dispersion of discrete reinforcing materials throughout a matrix. This method places too much reliance on the surface bond between matrix and reinforcing phase. By employing two continuous, interpenetrating materials, it is theorized...

Fall 2015
The present research has been done with the intent of evaluating the corrosion resistance and cracking susceptibility of some commercial candidate alloys that can be potentially used in Gen-IV supercritical water reactor (SCWR). The mechanism of the crack initiation in austenitic alloys exposed...
